FHS-632-4 is a flush-head self-clinching stud for installation in steel or aluminum sheets as thin as 0.020 in (0.51 mm), recommended for materials with Rockwell B hardness of 70 or less and Brinell hardness of 125 or less. The stud has a #6-32 thread, a nominal thread length of 0.203 in, and installs with a minimum centerline-to-edge distance of 0.157 in. The head projects 0.025 in above the sheet surface. It is available in aluminum, steel, or stainless steel and features a dimpled head for identification. The product is part of the FHS series that installs permanently by pressing into properly sized holes.
PEM® self-clinching studs are installed by placing them in properly sized holes in the sheets and squeezing into place with any standard press. The squeezing action embeds the head of the stud into the sheet. The metal displaced by the head flows smoothly and evenly around the ribs and into the annular groove – creating a flushhead assembly and securely locking the stud into the sheet with high torque-out and pushout resistances.
FH (flush-head) studs are available in aluminum, steel, or stainless steel . They are also available unthreaded on special order.
